An extra Bluetooth service provides an extra stream used for binary data.

Raj can help out

For instance: transmit power, etc.

Implementation of a Bluetooth-based video streaming protocol both-ways in/out of the monocle.

There are a lot of releases.
Most of which are early dev & debug versions.
Should I delete them?

About the behavior of the LEDs when booting:

• Blinking red when something goes wrong.
• Blinking green (steady at first) when everything is right and waiting for a connection.
• Turned off upon connection from the phone (normal operation)

To update later:

• update_available()
• update() end-end functionality

For battery_leve()

• Set MUX_SEL to batt_voltage
• Use a polynomial equation
• Set MUX_SEL back to high impedance

A last small check to make sure that as we enabled more things, the time we wait for the power rails to stabilize (startup time of all chips) do not get too dangerously close to the wait time we have.
Could lead to mismatch between production/dev version.

When disconnected a device does is not always discoverable through bluetooth: no UUID128 grabbed by ./serial_console.py.

No assert() or app_err() triggered though.

At times, Micropython triggers an internal assert().
Not sure where these are rooted from.
This happens when blasting the same command many times (~100x).

• memcpy issue
• cleanup makefile
• cleanup linker script
• replace asserts with handled error functions
• cleanup unused logging
• migrate i2c calls to new driver
• new, safer pmic on/off functions
• fix led functions

How it works on frame:

checkBatteryOrCharging()
{
  readADC();
  readCharging();
  if (charging || low_battery)
  {
    PMICPowerDownEverything();
    enableRTCWakeup(1000);

    // This will never return
    deepSleep();
  }
}

main()
{
  initialiseGPIO();
  initialiseI2C();
  initialiseADC();
  RTOSTask(checkBatteryOrCharging, 1000);
  checkBatteryOrCharging();

  // Only gets here if not charging
  PMICPowerUpEverything();
}

Turning them on while importing the module.
Implement power states at the same time.

• Desolder the battery cell of one of the boards.
• Measure the current.
• Turn as many things as possible off until the current is at its minimum.
• Implement the python calls for turning mode on
• Estimate battery life in this mode.

Different people have different body capacitance, so various sensitivity might help compensating different contexts.
I.e. "gloves mode".

status() and power()

• device.update_available()
• device.update() end-to-end
• fpga.update()

I could not reproduce the problem insofar, so keeping an eye on this.

Over-The-Air Device Firmware Upgrade.
Nordic provides something for Bluetooth for that.
Need integration with the current firmware image.
